Import Triples from selected File into current Model

This import wizard can be used to add the contents of a given RDF file to the model that is currently open (has the focus of the resource editor) in TopBraid Composer. To use it:

  1. Open the target file in Composer
  2. Open the Import wizard for the source file (e.g. right-click on it in the Project Explorer and then select Import > TopBraid Composer > Import Triples from this File into current Model)
  3. Read the description and click the Finish button to start
  4. The process can be stopped using the Stop button in the lower right corner of the wizard

The main use case of this feature is to load very large RDF (RDF/XML, Turtle or NT) files that would not fit into memory otherwise. You could create a target database, e.g. a TDB database, then then run this import wizard with the database being the selected model. All triples will be immediately streamed into the database, bypassing any buffers or caches. When done, you should save the database to make sure all triples have been written to the store, and then you may want to refresh all caches and views or re-open the file.
